Letters Patent N 93,7 83, dated August 17,Vv 1869.

The Schedule referred to in these Letters Patent .and making part o! the name.

To all whom it may concern.-

Be it known that I, SAMUEL WING, of Munson, in

the county of Hampden, and State of Massachusetts,

nioiily constructed, doesA not have the same effect in have inventeda new and useful Improvementin Hat- Shaping Machines; and I do hereby declare that the 'following is a full, clear, and exact description thereof',

which will' eiiableothers skilled 4in Ithe art to`makcr and use the saiiie, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to improvements iu that class of hat-shaping or pressing-machines in'whieh a rubber or other elastic diaphragm or bag is uscdto j press the body into the metal female mould, the sai'ne being distended by the pressure of Water. condensed air, or other equivalent means.

The invention consists in the application to s uch bags of` a metallic` supporting-ring, toinsure the ,proper format-ion of the square, or angles of the hat-bodies, as hereinafter fully specified. Figure l represents a-secti'onal view of the bag, hat, and mould, in their proper relative positions.

Figure 2 represents a detached section of my iinproved stitfenin'g-ring.

'Similar letters of reference represent corresponding parts.

The woven o r felted hatbodies, H, after being formed, are placed in the female die or mould I, (both shown in red,) and the India rubber, or other flexible and elastic vbag A, which is of a forni approximating that designed to be given to the said bodies, is placed between them, and the hat pressed between them by suitable means.

`B represents the space for the crown, and O the part whereon the brim is pressed.

For imparting the force necessary to suitably press the hat,the bag A is filled with corn-meal, mixed with water, ou the upper surface of'which pressure.

me, this 6th day of May, 1869,.

phragm may, if preferred, -be forced into the mould by atmospheric or hydraulic pressure.

The method of pressing with the bags, as -comthe angles at D as at the other parts of the surface,

whereby the bodies are not so well defined as they should be at these angles.

This result is due mainly, as I suppose, to the fact that the pressure being of a hydrostatic nature, has less area iii these angles to act upon, proportionately Vto Nthe resistanceof the bag, which is here greater',

owing to the form, than elsewhere.

"To overcoine this diiculty, I propose to introduce into these angles, and all others, iii bags of any forni,

adapted to hats of any shape, metallic angle-shaping bands, E, which, at all times, preserve the requisite shape of these bags in the angles, whether under the press or not; and to allow them to be self-adjusting to the size of the. holdei'sviiito which the bags are placed, I separate the rings, as at F, aiid apply rigidly tothe end of one part, by soldering or otherwise, a`v short section, G, lappingby the other end, whereon the latter inaywork back and forth to some extent, to fit into holders having slight variations of size.

I propose to apply these rings to the extension of the bags, and secure them,by placing an additional outer dressing, H, of India rubber, and vulcanizing it thereon.

Having thus described my invention,

Whatl I claim as new, and desire to secure by Letters Patent, is-

An elastic and flexible `hat-pressing bag, A, provided with metallic angle-rings, E, substantially as specified. v
